Serving and receiving in table tennis are of special significance. Ground stroke technology can develop players' ability to hold the opponent at the baseline, maneuver, and approach the front of the net and the net-front over-the-table stroke technology can effectively destroy the opponent's defense line, putting the opponent in a passive position. Compared to ground strokes and over-the-table strokes, serving is a more difficult technique to master because it involves more body parts and larger movements, requiring a higher degree of muscle coordination. However, despite this, mastering serving is not particularly difficult because the initiative of serving is in the player's own hands. Whether throwing the ball or swinging the racket to hit the ball is completely under their control. The server only needs to create good conditions for themselves and send the ball according to their intentions. To control serving with good conditions, in addition, everyone must control the strength of serving, and they must not serve dead balls.

Understanding the significance and importance of serving, let's get started and make a small automatic serving machine together.

Science Project:

 1. Recognize and prepare the necessary materials for the experiment.

Step 2: Install according to the instructions in the manual.

3, Install and debug.

 Scientific Principles:

 Its basic operating principle is to utilize the friction of a rotating wheel to impart a certain initial velocity to the ball.

1. When the power is turned on, the motor in the ball-feeding device starts working, driving the rotating wheel and sending the ball into the ball-dispensing device.

2. The ball is ejected from the blade wheel within the ball-dispensing device, traveling through the ball-dispensing pipe to reach the outlet of the machine head.

3. After the ball reaches the exit, the driving wheel rotates and friction with the ball to send it out.
